The Ideal Q385A-1020 pilot burner is a naked flame within the unit that is used to begin combustion of the gas coming into the main burner. When the appliance is switched on, the gas valve releases gas into the burner, which is then ignited by the pilot flame. The pilot flame operates in tandem with the printed circuit board and the rest of the pilot assembly to ensure that the gas is ignited safely and efficiently. It comes with additional fittings.
